DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1A and 1B, the structure of a canopy according to apreferred embodiment of the present invention includes a pillar 1, aslide connection block 2, an end portion connection block 8, a roof edgeframe 3, a roof center frame 4, a rod connection block 10, an upper headconnection block 5, a lower head connection block 6, and a roof cloth 7.

The pillar 1 is erected from the ground to support the canopy of thepresent invention. The pillar 1 is vertically erected in a multiplenumber to support a roof such that four pillars are installed for asingle unit canopy as shown in FIG. 1B, minimum six pillars areinstalled for a double unit canopy as shown in FIG. 2A, and minimumeight pillars are installed for a three-unit canopy. Also, as shown inFIGS. 2B and 2C, for a four-unit canopy arranged in a square form,peripheral pillars are installed so that a total of eight pillars areinstalled while a center pillar is removed.

As shown in FIGS. 2B and 2C, the multiunit canopy where the centerpillar is removed may be a single-roof multiunit canopy having a singleroof 100 where four pointed small roofs are formed, as shown in FIG. 2B,or a double-roof multiunit canopy having a double roof 110 where roofsare formed double to constitute a single pointed large center roof, asshown in FIG. 2C.

The slide connection block 2 is formed to encompass the pillar 1 andcapable of sliding up and down along the pillar 1. When the roof isunfolded, the slide connection block 2 slides up to a raised positionand is not lowered by being hooked by a key lever included in the slideconnection block 2.

When the roof is hinge folded, a user releases the key lever by pressingit so that the slide connection block 2 is freely lowered. Then the usergathers the pillars to hinge fold the roof edge frame 3 and the roofcenter frame 4.

Also, the roof edge frame 3 supporting the edge of the roof includes afirst rod 31 and a second rod 32. The first rod 31 pivots around the endportion connection block 8 of the pillar 1 and the second rod 32 pivotsaround the side connection block 2, so that the center portion thereofpivots in X form and capable of being hinge folded. At least two pairsof the roof edge frame 3 are connected for one side of the roof and aplurality of the roof edge frames are formed (eight pairs in thedrawing).

The roof center frame 4 supporting the center portion of the roofincludes four pairs of a first rod 41 and a second rod 42. The first rod41 pivots around a rod connection block 9 of the first rod 31 of theroof edge frame 3. The second rod 42 pivots around the rod connectionblock 10 of the second rod 32 of the roof edge frame 3. Thus, the centerportion of the first and second rods 41 and 42 pivots in X form andcapable of being hinge folded.

When the roofs are unfolded, to make the height of the upper headconnection block 5 higher than that of the roof edge frame 3, the rod ofthe roof center frame 4 is longer than the roof edge frame 3 and thefirst rod 41 of the roof center frame 4 is longer than the second rod42, so that a roof top can be formed with no additional vertical rod atthe center of the roof.

The upper head connection block 5 pivots around the first rod 41 of eachof a plurality of the roof center frames 4, thus forming the outer topend of the roof. The lower head connection block 6 pivots around thesecond rod 42 of each of the four roof center frame 4, thus forming theinner top end of the roof.

The roof cloth 7 forms a sunshield cover covering the roof edge frame 3and the roof center frame 4, which can drain rainwater during raining.

Thus, as shown in FIG. 1B, when the user widens a space between fourpillars 1, the slide connection block 2 is raised. Also, an anglebetween the first and second rods 31 and 32 of the roof edge frame 3narrows and the length thereof extends. Simultaneously, an angle betweenthe first and second rods 41 and 42 of the roof center frame 4 connectedto the roof edge frame 3 narrows and the length thereof extends. Sincethe first rod 41 of the roof center frame 4 is longer than the secondrod 42 thereof, the upper head connection block 5 is raised higher thanthe roof edge frame 3.

Next, when the user widens a space between the pillar 1 at its maximum,the slide connection block 2 is not lowered by being hooked by the keylever. Accordingly, the roof edge frame 3 and the roof center frame 4are fixed. When the user covers the roof cloth 7 over the roof edgeframe 3 and the roof center frame 4, as shown in FIG. 1A, the canopyaccording to the present invention can be completed.

Then, when the user releases the key lever by pressing it to lower theslide connection block 2, the pillar 1 is closed to completely hingefold the roof edge frame 3 and the roof center frame 4so that volume isminimize and the canopy is easily kept and carried.

In the meantime, as shown in FIG. 2D, an upper roof column 120penetrating the upper head connection block 5 and capable of slidingwith respect to the upper head connection block 5 is installed on thelower head connection block 6. An elastic spring 121 is installed underthe upper roof column 120 and inside a lower roof column 120-1 to becapable of adjusting height of the upper roof column 120. To adjustdisplacement of the elastic spring 121, a rotary handle 122 can berotatably installed at the lower head connection block 6, so that oneend of the rotary handle 122 penetrates the elastic spring 121 and isfixed to an end portion of the elastic spring capable of freely rotatingand, when the other end thereof rotates, a nut 120-2 screw reciprocateswith respect to the lower head connection block 6. However, as shown inFIG. 1B, the upper roof column 120 can be omitted.

As shown in FIGS. 2K and 2L, an S portion of the pillar 1 includes aninner pipe 1 b inserted in an outer pipe 1 a capable of sliding thereinto adjust the height of the pillar 1. A key lever 133 elastically hookedin a through hole 1 c formed in the outer pipe 1 a is installed at theinner pipe 1 b. A fixing block 131 fixing the inner and outer pipes 1 band 1 a is installed at the outer pipe 1 a.

The key lever 133 may be a circular pipe snap button applied to thepillar 1 having a circular pipe shape according to use thereof, in whicha spring 141 having a round strap shape is installed at a circularcolumn type inner frame 140, as shown in FIGS. 2E and 2F, or arectangular pipe snap button applied to the pillar 1 having arectangular pipe shape, in which a trigger type spring 151 (a U shapeshown in FIGS. 2G and 2H and an L shape shown in FIGS. 2I and 2J)installed at a rectangular column type inner frame 150, as shown inFIGS. 2G, 2H, 2I, and 2J.

The round strap spring 141 shown in FIG. 2F is not necessary for theinner frame 140. The spring 141 can be solely installed without theinner frame 140 at an installation position which is relatively shallowfrom the end portion of the pillar.

To prevent damage to a hand of a user, as shown in FIGS. 2K and 2L, thefixing block 131 includes a main body 132, the slide type key lever 133,an elastic spring 134, and a key lever handle 135. The main body 131 isan injection molding block where a rail is formed. The slide type keylever 133 slides on the rail in the main body 131. The slide key lever133 is a column type injection block of which a leading end portionpenetrates the inner pipe 1 b of the column 1 and is fixed there whenthe slide key lever 133 slides forward. The elastic spring 134 isinserted around a tailing end portion of the slide type key lever 133and installed between a fixing cap 136 and the slide type key lever 133,so that a restoration force is applied in a direction to advance theslide type key lever 133.

The key lever handle 135 is a handle having one end screw coupled orcoupled to a screw hole formed in one side of the slide key lever 133and the other end protruding from a slide hole 137 formed in one side ofthe main body 132. A user moves the slide type key lever 133 backward soas to make the inner pipe 1 b free.

Thus, the canopy is kept by inserting the inner pipe 1 b into the outerpipe 1 a of the pillar 1. When the canopy is to be used, the user pullsthe inner pipe 1 b and then the inner pipe 1 b and the outer pipe 1 aare automatically fixed by a key lever 133 penetrating the through holedue to the restoration force. To keep and disassemble the canopy, theuser holing the key lever handle 135 moves the slide type key lever 133backward so that the inner pipe 1 b is made free to be inserted.

In the meantime, as shown in FIGS. 3A. 3B, 3C, 3D, and 3E, the structureof the canopy according to the present invention is not limited to apyramid type roof adopting an “A” front truss shown in FIGS. 1A, 3A, and3B, but a slate roof shown in FIG. 3B, a cross type roof shown in FIG.3C, a cross-pyramid type roof shown in FIG. 3D, and a modifiedcross-pyramid type roof shown in FIG. 3E. Each of the center portionscan be applied by modifying the center portions shown in FIGS. 7A, 7B,and 7C. To reinforce truss, a wire or a steel bar can be connected toaround the upper end head block.

The slate roof of FIG. 3B is designed such that the rods of the highroof center frame at the center peak of FIG. 1B are assembled such thatthe front side surface and the rear side surface identically cross. Theshape of the peak can vary by designing the vertical length andhorizontal length of the roof edge frame the same or different from eachother (in which “A” and “B” front truss can be applied).

The cross roof of FIG. 3C can be designed by exchanging and assemblingthe rods of the roof center frame at the left and right side surfaces inFIG. 3B. Thus, rain or snow can flow down toward the four corners fromthe central peak (in which “B” front truss of FIG. 3B can be applied).

The cross-pyramid roof of FIG. 3D can be designed by making the centralpeak, that is, the pipe of the roof center frame, quite high. Thus, thecanopy can be used in an area having much snow or rain, (in which “B”front truss of FIG. 3B can be applied).

The modified cross-pyramid roof of FIG. 3E can be designed by removingthe peak portion at the left and right side surfaces of FIG. 3D so as tomaintain the height of the middle portion at the front and rear sides(in which “B” front truss of FIG. 3B can be applied).

In FIGS. 3A-3E, in each of the roof edge frames in the “A” front truss,the “A” side truss, the “B” front truss, and the “B” side truss, thesecond rod is longer than the first rod.

In addition to the above examples, the structure of the canopy of thepresent invention can be applied to all canopies having a variety ofshapes and types.

Also, in addition to the canopies shown in FIGS. 3A, 3B, 3C, 3D, and 3E,by installing two more pillars 1 and installing the roof edge frame 3and the roof center frame 4 to be extended, two pairs of the upper headconnection blocks 5 and the lower head connection block 6 are formed intwo roof form.

In addition, as necessary, the pillar 1, the roof edge frame 3, and theroof center frame 4 can be further extended to form multiple units suchas three units or four units.

As shown in FIG. 5A, the slide connection block 2 operated by indirectlypressing a slide key lever 101 to prevent a damage to a finger of a userincludes a main body 12, the slide key lever 101, an elastic spring 30,and a key lever fixing tool 22.

That is, the main body 12 is an injection molding block where acylindrical rail 20 is formed in a lower portion thereof. The slide keylever 101 is a column type injection block which is inserted in the rail20 of the main body 12 capable of sliding. When the user presses theslide key lever 101 and slidingly advances the same, a leading endportion of the slide key lever 10 is inserted in a through hole 2 aformed in the pillar 1.

Also, the elastic spring 30 is inserted around the leading end portionof the slide key lever 101 and installed between the main body 12 andthe slide key lever 101. The elastic spring 30 generates a restorationforce in a direction in which the slide key lever 101 is retreated.

The key lever fixing tool 22 is a latch caught by a hook groove 10 aformed in the slide key lever 101. The key lever fixing tool 22 is akind of stopper which is inserted in a vertical hole 101 a formed in afixing cap 101 covering and fixing the slide key lever 101 and descendsby the weight thereof. The leading end portion of the key lever fixingtool 22 is caught by the hook groove 10 a of the slide key lever 101 sothat the key lever fixing tool 22 locks the slide key lever 101 in anadvanced state.

Thus, when the user is to descend the slide connection block 2 hooked bythe slide key lever 101, the key lever fixing tool 22 locking the sidekey lever 10 is lifted to make the slide key lever 101 move freely. Asthe slide key lever 101 retreats by the elastic spring 30, the leadingend portion of the slide key lever 101 is separated from the throughhole 2 a formed in the pillar 1. Then, the pillar 1 is separated fromthe slide connection block 2 so that the slide connection block 2 canfreely descend.

When the slide connection block 2 is to be fixed to the pillar 1, theuser pushes the rear end portion of the slide key lever 101 to insertthe leading end portion of the slide key lever 101 into the through hole2 a of the pillar 1 so that the slide connection block 2 is fixed to thepillar 1. Then, to prevent retreat of the slide key lever 101, the keylever fixing tool 22 is naturally lowered by the weight thereof in thevertical hole 101 a of the fixing cap 101 so as to be fixedly inserted.

As shown in FIG. 5B, the slide connection block 2 operated by indirectlypulling a key lever handle 10 c to prevent a damage to a finger of auser includes the main body 12, the slide key lever 101, the elasticspring 30, and the key lever handle 10 c.

That is, the main body 12 is an injection molding block where thecylindrical rail 20 is formed in a lower portion thereof. The slide keylever 101 is a column type injection block which is inserted in the rail20 of the main body 12 capable of sliding. When the slide key lever 101slidingly advances, a leading end portion of the slide key lever 10 isinserted in the through hole 2 a formed in the pillar 1.

Also, the elastic spring 30 is inserted around a rear end portion of theslide key lever 101 and installed between the fixing cap 101 and theslide key lever 101. The elastic spring 30 generates a restoration forcein a direction in which the slide key lever 101 advances.

The key lever handle 10 c is a handle having one end screw coupled orfixed to a screw hole 10 b formed in the side surface of the slide keylever 101 and the other end protruding from a slit 10 d formed in a sidesurface of the main body 12. The hinge of the pillar 1 is made free whena user retreats the slide key lever 101 in an advance state.

Thus, in order to descend the slide connection block 2 hooked by theslide key lever 101, the user pulls the key lever handle 10 c to retreatthe slide key lever 101 and the leading end portion of the slide keylever 101 is separated from the through hole 2 a of the pillar 1. Thus,the locking between the pillar 1 and the slide connection block 2 isreleased so that the slide connection block 2 can be freely lowered.

As shown in FIG. 5C, as another preferred embodiment of a key lever forthe slide connection block, the slide connection block 2 has a structureto prevent a damage to a finger of a user by indirectly pressing arotary key lever 70. The slide connection block 2 includes the main body12, a rotary key lever 70, and an elastic spring 80.

That is, the main body 12 is an injection molding block where a guideplate 70 a is formed at one side thereof. The rotary key lever 70 is arotary plate type injection block which can pivot around a pivot shafton the guide plate 70 a of the main body 12. When the user raises theslide connection block 2 to open the canopy, the rotary key lever 70 isrotated by the elastic spring 80 and a tip portion at one side of therotary key lever 70 is inserted in the through hole 2 a formed in thepillar 1.

The elastic spring 80 is inserted around the other tip end portion ofthe rotary key lever 70 and installed between the main body 12 and therotary key lever 70. The elastic spring 80 generates a restoration forcein a direction in which the rotary key lever 70 is rotated.

Thus, in order to lower the slide connection block 2 hooked by therotary key lever 70, the user presses a handle portion of the rotary keylever 10 to rotate the rotary key lever 10 in the reverse direction.Then, the tip end portion of the rotary key lever 70 is separated fromthe through hole 2 a of the pillar 1. Thus, the locking between thepillar 1 and the slide connection block 2 is released so that the slideconnection block 2 can be freely descend.

When the slide connection block 2 is to be fixed to the pillar 1, theuser simply releases the handle portion of the rotary key lever 70 andthe tip end portion of the rotary key lever 70 is pushed by the elasticspring 80 to be inserted in the through hole 2 a of the pillar 1. Thus,the slide connection block 2 can be fixed to the pillar 1.

In addition to the above exampled, various types of fixing means capableof locking the slide connection block 2 and the pillar 1 can be adoptedwithin a range of the concept of technology of the present invention,which is easily modified or altered by one skilled in the present art.

The slide connection block 2, the end portion connection block 8, thefirst rod connection block 9, the second rod connection block 10, theupper head connection block 5, and the lower head connection block 6 areplastic injection structures or welding structures according topurposes. Also, according to the shape of the rod, an indented shapehaving a rectangular, square, circular, or oval shape is possible. Ifnecessary, the block can be manufacture to have an open upper side. Avariety of embodiments can be manufacture as shown in FIGS. 4A, 4B, 4C,4D, 5A, 5B, and 5C.

That is, as shown in FIG. 4A, an arm 34 is formed such that the firstand second rods 31 and 32 are pivot coupled by a hinge shaft 33penetrating a pin hole 31 a formed in the first and second rods 31 and32 and a pin hole 33 a formed in the connection block.

Here, a spline groove having a corrugated shape are formed on an innerdiametric surface of the pin hole 31 a formed in the first rods 31 and31 and the second rods 32 and 42. A spline protrusion having acorrugated shape corresponding to the spline groove 35 a is formed on anouter surface of the hinge shaft 33 penetrating the pin hole 31 a.During rotation of a hinge, a pin is rotated in the hinge where thehinge shaft 33 and the first rod 31 or the second rod 32 are connected.A cap or pin 36 is fixed to an end portion of the hinge shaft 33 to makecoupling firm.

The pin hole 31 a formed at the end portion of the first and second rods31 and 32 is preferably formed by directly pressure punching the endportion of the first and second rods 31 and 32. As shown in FIG. 4A, thepin hole 31 a is formed in a separate injection mold 35 and the pin hole31 a is formed at the first and second rods 31 and 32. Thus, the hingeshaft 33 penetrates the pin hole 31 a of the injection mold 35 and thepin hole 31 a of the first rod 31 or the second rod 32 so that theinjection mold 35 and the first rod 31 or the second rod 32 can befirmly fixed by capping the end portion of the hinge shaft 33 using apin or cap.

As shown in FIGS. 6A and 6B, in the structure of the canopy according toanother preferred embodiment of the present invention, a ventilatingopening 55 is formed at the sharp center of the roof cloth 7. The upperhead connection block 5 protrudes upward by penetrating the ventilatingopening 55. A hinged sunshield roof rib 51 is formed at the upper headconnection block 5 separated a predetermined distance from theventilating opening 55, so that a double storied sunshield roof 52 isinstalled.

The double storied sunshield roof 52 has a diameter greater than that ofthe ventilating opening 55 so that sunshine falling on the ventilatingopening 55 can be completely shielded.

Accordingly, a user can keep the canopy by folding the frame using thehinge and opens the canopy by slightly widening the pillar 1, as shownin FIG. 6B. Then, as shown in FIG. 6A, the canopy is completed bycovering the completed double storied sunshield roof 52 with the roofcloth where the ventilating opening 55 is formed.

The sunshield roof rib 51 supporting the double storied sunshield roof52, as shown in FIG. 6B, includes a radial sunshield roof rib 511 and ahinged sunshield roof rib 512. The radial sunshield roof rib 511 forms aframe for the sunshield roof 52 while the hinged sunshield roof rib 512supports opening of the radial sunshield roof rib 511 when the frame isopened.

Also, the above two storied sunshield roof 52 can be installed as adouble unit canopy by further installing two more pillars 1, the roofedge frame 3 and the roof center frame 4 to form two units of the upperhead connection block 5 and the lower head connection block 6, fourcorner reinforcement bars 53 shown in FIG. 5B when the strength needs tobe reinforced, and one more double storied sunshield roof 52. Inaddition to the above structure, if necessary, multiple units such asthree units or four units can be formed by further installing the pillar1, the roof edge frame 3, the roof center frame 4, and the cornerreinforcement bar 53.

As shown in FIGS. 7A, 7B, and 7C, the shape of the first rod 41, thesecond rod 42, and the third rod 53 of the roof center frame 4 of thehinged sunshield roof rib 512 of which one end pivots can bemanufactured in various ways according to the purpose or the strength ofwind. As shown in FIG. 7A, the first rod 41 can pivot with respect to aslide bar which slides to push and erect the second rod 42. As shown inFIG. 7B, the second rod 42 can pivot with respect to the first rod 41which slides to pull and erect the first rod 41. As shown in FIG. 7C,the first rod 41 and the second rod 42 can pivot crossing each other in“X” form. Also, the third rod 53 can be included or excluded accordingto the strength or purpose.
